. FASTENNG DEVICE FOR RUBBERS.

Specification o' Letters Patent.

Patented July 7, 190s.

Application led April 12, 1907. Serial No. 367,749.

To-a-ll whom it may concern.:

Be 1t known that l, HENRY R. NELSON, of Walnut Grove. Redwood county,Minnesota,

have invented certain new and useful Im-A rovements in Fastening Devicesfor Rubers, of which the following is a specification.

In walking over a muddy road or street, the over shoe or rubber willfrequently stick in the mud and be pulled off the shoe as the foot islifted in the act of walking.

The object of my invention is to provide means for securing the rearportion. of the rubber or oversl'ioe to the shoe to prevent its beingaccidentally pulled off.

The invention consists generally in variou constructions, andcombinations, all as hereinafter described and particularly pointed outin the claims.

In the accompanying drawing, Jforming part of this specification, Figure1 is a view o f the foot and ankle showing the rubber or overshoe on theshoe with the foot raised in the act of taking a step, my inventionbeing illustrated in place on the `shoe.A Fig. 2 is an edge view of theclamp. Fig. 3 is a rear view Showing the clamp closed. Fig. 4 is asimilar view showing the clamp open. Fig. 5 is a sectional view on theline a-- of Fig. 3. Fig. 6 is a detail view showing curve in the aws toconform them to the curve of the rubber. Fig. 7 is a sectional view onthe line y-y of Fig. 3. Figs. 8 and 9 are detailed ,views of the clip orfastening device by neans of which the loose end of the string issecured.

In the drawing, 2 represents a shoe and 3 a rubber or overshoe. 4 and 5are `jaws,

referably of metal loosely secured together y a ivot pin 6. The jaw 4.is preferably provi( ed with a series of teeth 7 on its lower edge. Theup er cn'd of the aw 4 has an eye 8 formed therein and a cam .9 that isada ted to engage the jaw 5 and force the ends of the jaws apart andcauso their lower edges to be moved toward one another to gripanymaterial that may be inserted between them. If the edges are swung tothe position indicated in Fig. 4, there will be sutllcient moveto allowthe upper edge of the counter portion of the rubber to be insertedbetween the edges and then when the law 5 is swung to the positionindicated in ig. 3, the edffe vof the rubber will be gripped and firmlyAlield. The jaw 5 also has an eye 1() and a string 11 is threadedthrough the eyes 8 and 10 and is of suflicient length to extend aroundthe ankle and the upper of the shoe.

A plate 12 is attached to one end of the' string and is provided withoppositely arranged spring tongues 13, under which the free end of thestrm is inserted and drawn taut and held securely b the tongues until itis desired to remove tie. device from the foot. .The plate with the sring tongues permits the clam s to be easi y and quickly ut in place ont e shoe or removed therefrom without the necessity oftying or untyin aknot.

do not wish to be confinedv to the particular form of clamping jaw-sillustrated herein as the. same are capable of. modification. and stillhave substantially the same functions and other means may be employedfor securing the loose end of the string without departing from thespirit of my invention.

.I claim as my invention:

1. A fastening device for rubbers comprising pivtally connected jawshaving curved lower edges to conform toI thc curve of the rear portionof the rubber,-one of said jaws having a series of teeth, a cam mountedlon one of said jaws and adapted to engage the other to force the lowered es together and a string attached to sai jaws and adapted to extendaround the ankle, substantially as described.

2. A fastening device for rubbers, comprising disk-shaped jaws 4 and 5centrally pivoted together and having curved lower edges, one of saidcurved lower edges having a series of teeth and said jaws havingprojections with eyes or loops formed therein, one of said jaws having acam surface to engage the projection on the other jaw and hold them intheir clamping position, and a oord passing through said eyes or loopsand adapted to be secured around the ankle, substantially as described.

3. A fastening device for rubbers, comprisug jaws centrally pivotedtogether and jaws and extending around the ankle," to

having lower edges between Which the' edge secure the device to thefoot. .10 v oit the ruhher is inserted, one of said jaws In WitnessWhereof,Iliave hereuntoset my being adapted to swing in a plane parallelhand this 6th day'orl A ril 1.907. substantially Vith Ithe plane of theother jaW v HE RY R. NELSN.

and one jaw having a @am edge to engage the Witnesses: y

other jaw, whereby they Will be held in their H. O'. GARLo'oK,

looked position, and means attached to said C. J. NELSON
